Just for future reference, I wanted to update this post to explain the problem that occurred, why it occurred and how I fixed the situation.
These plants had germed and planted in jiffy pots with promix bx. I had read several people on this site recommending that growing medium yet I had not done enough research to realize that promix requires magnesium supplement from seedling. I had been watering these plants with straight water the first 3 weeks and had only began to supplement with GH Micro, Grow and Bloom the previous week. Needless to say, the girls had gotten some serious magnesium deficiencies before I began seeing it in the leafs. So, the solution was I immediately stopped all nutrient supplementation except for Cal/Mag, I transplanted to larger pots(not needed but was going to happen anyways) and I was adding 10ml/gallon of RO water Cal/Mag and watering as normal 3 times for the remainder of the week. That was with 10% runoff. After the week was up and I began noticing some good color come back in the leafs I started nutrient supplementation again at 1/2 strength along with 10ml/gallon of Cal/Mag continued at each watering. The plants have all taken back off and look wonderful after a week of supplementation.
This happened to be one of those newbie mistakes that happen but thanks to some quick responses from AFN and quite a bit of due diligence searching the internet I was able to correct the problem before it got out of hand. Thanks to everyone that replied! Much love to all of you. Hopefully this post will help another member down the road!
